The UK event takes place from September 5th through the 8th, and Elton will be the closing night headliner.

The Elton boot auction is part of eBay's "Big Charity 50" fundraiser in support of Amnesty International.

John says he's proud to support the cause, explaining that "basic human rights are being violated the world over on the basis of race, gender, religion or sexual orientation," and Amnesty International does "an amazing job in bringing the world's attention to this abuse."

The auction, at eBay.com, closes on September 1st. Go get your bids in!
